The HOYA Sq100 polarizer can be rotated inside the frame to control light reflections and color saturation. With its large diameter of 86mm, the polarizer filter won't cause any vignetting with most lenses. HOYA's special water repellent multi-coating is applied to the polarizer's optical glass, making cleaning easy and stress-free.
The polarizer adopts a high transparency polarizing film for fast shutter speed. This translates to no less than nearly 1/2 stop more light entering the lens while yielding the same polarization effect. An absolute advantage for shooting in low light conditions.
For using the polarizer, screw it into the geared adapter and attach the geared adapter to the lens. Attach the HOYA Sq100 holder to the geared adapter so that the geared wheel come into the contact with the gear of the geared adapter.
In order to avoid purchasing one of those counterfeit filters we highly recommend to purchase only from official retailers that are recognized by HOYA's official global distributors. Prior the purchase kindly inquire and verify whether a retailer is authorized by HOYA global distributors. You may find the contact in the HOYA global distributors list.
